Warren suggested in one tweet that the Republicans are trying to “move on” to Gorsuch, a day FBI Director James Comey testified to the House Intelligence Committee that the FBI is investigating Trump's campaign and Russia.

Neil Gorsuch is up for a lifetime appointment to the Supreme Court from a President whose campaign is under FBI investigation.

Warren joins a growing number of prominent Democrats, including House Minority Leader Chuck Schumer (D-N.Y.) and Democratic National Committee Chair Tom Perez, who say the ongoing Kremlin investigation means that Gorsuch's confirmation vote should be put on hold.

The committee will likely vote on Gorsuch’s nomination the first week of April before it goes to a full Senate vote.
